A honeycomb body includes at least one housing and a honeycomb structure for a waste-gas purification system having at least one sheet metal material. The sheet metal material has elevations in at least one section and an edge contour enclosing the elevations. A portion of the area of the elevations in the at least one section is at least 80%. A particle separator, a catalyst carrier body and a motor vehicle having the honeycomb body are also provided.

A nonwoven fabric for exhaust-gas treatment includes a multiplicity of metallic filaments having at least two types of different contours of the metallic filaments. An exhaust-gas purification device includes a channel structure through which exhaust gas can at least partially flow. The channel structure is made at least partially with such a nonwoven fabric. A method for producing a nonwoven fabric for exhaust-gas treatment is also provided.

A sheet-metal layer includes anti-diffusion structures made of a high-temperature-corrosion-resistant steel having a longitudinal direction, upper and lower surfaces, a thickness of 0.015 to 0.1 mm and discontinuous microstructures extending approximately in the longitudinal direction. The microstructures have a structure height (0.02 to 0.1 mm), a structure length (2 to 10 mm), a structure width (0.2 to 1 mm), a longitudinal spacing (greater than 2 mm), formed by interruptions, from the nearest microstructure aligned approximately in the longitudinal direction and a lateral distance (1 to 10 mm) from the nearest laterally adjacent microstructure. Some of the microstructures project out of the sheet-metal layer toward the upper surface and some toward the lower surface. The microstructures cause each straight theoretical line extending across the sheet-metal layer perpendicularly to the longitudinal direction to intersect at least two microstructures projecting toward the upper surface and two microstructures projecting toward the lower surface.
